Abstract

Purpose

The aim of this paper is to develop a methodology for assessing search results retrieved from different sources.

Design/methodology/approach

This is a two phase method, where in the first stage users select and rank the ten best search results from a randomly ordered set. In the second stage they are asked to choose the best pre‐ranked result from a set of possibilities. This two‐stage method allows users to consider each search result separately (in the first stage) and to express their views on the rankings as a whole, as they were retrieved by the search provider. The method was tested in a user study that compared different country‐specific search results of Google and Live Search (now Bing). The users were Israelis and the search results came from six sources: Google Israel, Google.com, Google UK, Live Search Israel, Live Search US and Live Search UK. The users evaluated the results of nine pre‐selected queries, created their own preferred ranking and picked the best ranking from the six sources.

Findings

The results indicate that the group of users in this study preferred their local Google interface, i.e. Google succeeded in its country‐specific customisation of search results. Live Search was much less successful in this aspect.

Research limitations/implications

Search engines are highly dynamic, thus the findings of the case study have to be viewed cautiously.

Originality/value

The main contribution of the paper is a two‐phase methodology for comparing and evaluating search results from different sources.

Abstract

Purpose

This study aims to investigate the interrelationships and elasticities between the production of renewable energy (RE) and three key variables: oil prices, gross domestic product (GDP) and carbon dioxide (CO2) emissions.

Design/methodology/approach

The research uses panel data and time-series analyses for 10 developed and 16 emerging countries for the period 1976–2018, to identify panel and country-specific elasticity of RE production and dynamic causal relationships between these variables. The study uses an autoregressive distributed lag model to determine the long- and short-run dynamics between RE production and the three variables in each country.

Findings

Results show a long-run elasticity between RE and GDP, and short-run dynamics between RE and oil prices and CO2 emissions in the developed countries. Whereas in the emerging countries category, there were long-run relationships between RE and GDP, CO2 emissions and oil prices.

Practical implications

Results of this study are in fact crucial and can be applied in the drafting of resilience policies to tackle energy vulnerability as well as sustainable growth. The study results will inform and guide governments on the right policies to stimulate RE production in their own countries in the interests of both their national security and sustainable development globally.

Originality/value

This paper attempts to contribute to the literature in at least two ways. First, research on identifying common determining factors, including socioeconomic factors, in both emerging and advanced economies is considerably scarce. Most of the previous research in this field has focused only on the absolute value of RE production in a particular geographical area. Second, many studies have focused on RE consumption. This research differs from them by focusing on the production of RE. Thus, the main contribution of this study is to fill these gaps. The study also presents novel empirical evidence to determine RE production elasticity from 26 countries.

Abstract

Purpose

This paper aims to examine the non-linear impact of inflation on financial development, and the moderating role of GDP in the relationship between inflation and financial development in a panel of 125 countries.

Design/methodology/approach

It employs the dynamic common correlated effects (CCE) that can control for heterogeneity and cross-sectional dependence. This technique enables us to conduct both panel and country-specific analyses.

Findings

Though there is no significant evidence that inflation has a non-linear impact on financial development in the panel, the country-specific estimations reveal that inflation has a non-linear impact on financial development in 66 countries. The results also show that GDP mitigates the detrimental effect of inflation on financial development in 45 countries. An insight into the non-linear relationship between inflation and financial development is crucial for policy decision-making. Besides, knowledge of the moderating role of GDP in the relationship between financial development and inflation is fundamental for policy formulations.

Originality/value

Although the extant literature has shown that the inflation rate plays a negative role in financial development, the literature overlooked the non-linear relationship between the two variables. Besides, the studies have not considered the role of GDP in moderating the impact of the inflation rate on financial development. This study fills these gaps in the existing body of finance literature.

Abstract

The authors evaluate financial stability and capital flows management objectives of capital controls in the context of four capital control events: removing or imposing controls on capital inflows and removing or imposing controls on capital outflows. The authors use synthetic control method to solve the endogeneity problem stemmed from the timing of capital control implementation. The authors find new evidence that capital controls are not consistently effective in reaching financial stability outcomes but are consistent in reaching capital flows management outcomes. The authors compare our results to estimates using difference-in-difference (DID) and carry out placebo analysis. Finally, we use synthetic DID to correct for the parallel trend bias and show that the results still hold.

Abstract

There are two important determinants in the banking system which directly affect the number of credit deliveries to the economy in the first round and impact the growth and developmental status of the economies in the second round. They are the amount of non-performing assets (NPA) and the number of banking funds invested in the governments’ securities. The present chapter, thus, focuses on the trends of these two and their associations with the credit, GDP and human development of the countries. First, it develops a basic theoretical structure of credit creation in the banking system and then develops theoretical linkages among the two lead variables, NPA and investment, in relation to the rest of the economy. Then, it goes for empirical exercises from the perspectives of the descriptive statistical analysis. The trends of NPA and investment show rising trends in almost all countries. Furthermore, it is found that the signs of correlation coefficients between the two with credit, GDP and HDI are positive in most cases of the list of developing countries and negative in some cases of the list of developed countries.

Abstract

Purpose

This paper aims to examine the stock return behaviour around the bonus issue announcements in eight emerging markets for 2010–2019 by addressing the signalling, cash substitution and liquidity hypotheses.

Design/methodology/approach

Besides using the standard event study technique to test the presence of an anomaly, country-based regression analyses are performed. Firm-specific factors are used to understand the motive behind the anomaly observed pre- and post-announcement periods. Also, the Amihud illiquidity measure examines the liquidity hypothesis, while standardized profitability and investment ratios compare the long-run operational performance of bonus issuers to test the validity of signalling.

Findings

The findings provide evidence that abnormal returns can be detected ten days before the announcement in some countries, which is a sign of information leakage. The presence of the effect continues only in two countries after the announcement is released. The size of the bonus issue is found strongly significant in most countries, while a weak relation between abnormal return and other factors is detected. Moreover, the signalling hypothesis does not hold in the sense of long-run profitability increase, while liquidity assertion is partially presented.

Research limitations/implications

Due to an inadequate number of announcements in other emerging markets, the number of sample countries is limited by eight.

Originality/value

The research is novel regarding analyzing a wide range of emerging countries with various variables. Also, the paper is distinguished from other studies by applying multiple set of regressions under nine different event windows.

Abstract

This chapter studies trends in income distributions and inequality in the European Union using data from the European Union Statistics on Income and Living Conditions. The author models the income distribution for each country under a Dagum distribution assumption and using maximum likelihood techniques. The author uses parameter estimates to form distributions for regions defined as finite mixtures of the country distributions. Specifically, the author studies the groups of ‘new’ and ‘old’ countries depending on the year they joined the European Union. The author provides formulae and estimates for the regional Gini coefficients and Lorenz curves and their decomposition for all the survey years from 2007 through 2011. The estimates of this study show that the ‘new’ European Union countries have become richer and less unequal over the observed years, while the ‘old’ ones have undergone a slight increase in inequality which is however not significant at conventional levels.

Abstract

Purpose

The purpose of this paper is to investigate the impact of the technology acceptance model, privacy concerns and demographic factors on intention to use (ITU) social networking sites (SNSs).

Design/methodology/approach

A questionnaire survey was developed and administered to a convenience sample of 838 university students.

Findings

The findings indicate that perceived privacy, demographic factors and perceived usefulness (PU) have a significant effect on the ITU SNSs, and that age does not moderate the relationship between perceived ease-of-use and PU.

Originality/value

This study confirms the growing importance of SNSs. It also provides social networking service providers with insights into user intentions towards such networks.

Abstract

Purpose

Individuals' health is considered one of the major determinants of higher levels of productivity and economic development. Over the past century, the widespread occurrence of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) has been a serious threat to economic development around the globe and has caused a dramatic fall in the life expectancy rate in many nations. This is the first study that examines the impact of HIV prevalence on health expenditure at the national level employing two linear and nonlinear autoregressive distributed lag (ARDL) models and simultaneously tests the long-run and short-run relationship for five selected developed countries. The authors employ annual data from 1981 to 2016. They find that HIV prevalence has a significant impact on health expenditure in the short-run and long-run in all five countries using the linear model and four of the countries in the nonlinear model. They find that HIV/AIDS prevalence has a significant short-run and long-run asymmetric impact on health expenditure of almost all selected developed economies.

Design/methodology/approach

The authors are employing two linear and nonlinear ARDL models and simultaneously test the long-run and short-run relationship for five selected developed countries.

Findings

The authors find that HIV/AIDS prevalence has a significant short-run and long-run asymmetric impact on health expenditure of almost all selected developed economies.

Originality/value

To the best of the authors’ knowledge, this is the first research work that empirically examines the link between HIV prevalence and health expenditure for this group of countries using linear and nonlinear ARDL approach for short run and long run.

Abstract

Purpose

The paper aims to report findings from research conducted that illustrates cross-cultural differences and similarities on the role obstacles, as defined by leadership antecedents, play in the levels of resilience found in leaders. While research has demonstrated a link between obstacles and the development of resilience in leadership, previous studies have not looked at whether this link exists across cultures and what differences or factors might affect this link.

Design/methodology/approach

The research provides additional evidence that the types of developmental experiences and the level of self-differentiation in the leader relates to the levels of resiliency within a leader. Furthermore, the research examines cultural differences in the findings and offers possible explanations for them. The study reflects responses from 365 participants (151 from USA, 112 from India and 102 from Germany). The study uses leadership antecedent categories, the Differentiation of Self Inventory, Short Form and the Connor Davidson Resilience Scale. Demographic information on participants included sex, age, level of education, years of leadership experience and industry.

Findings

The results demonstrate that resiliency is positively correlated with both the leadership antecedents and differentiation of self. In light of the research findings, the authors highlight the relationship between resiliency and the leadership antecedents, while providing rationale for cultural differences in this relationship, and highlight the relationship between resiliency and differentiation of self, while providing rationale for cultural differences in this relationship.

Research limitations/implications

The research implications include being able to determine whether a leader’s cultural identity has any effect on the development of resilience through hardships. Additionally, the research has the ability to have more generalized results, as the study looks at leaders across three distinct cultures. The study has two major limitations. First, the study was conducted with a convenient sample, which may not be a true representation across the entire culture. Second, the study only looks at three distinct cultures, which represent three of the ten major cultural clusters in the world, according to the leadership literature.

Practical implications

If leadership developers can begin to understand the interplay between developmental antecedents and the development of resilience, training can be tailored more specifically, even within distinct cultures. Additionally, understanding how differing cultures develop resilience and understand hardships as a part of that development, researchers can begin to isolate other variables that contribute to the development of resilience and other desirable leadership attributes, regardless of cultural background.

Originality/value

The study’s findings provide an additional argument for why obstacles and developmental experiences are a logical and necessary part of the formation process for leaders. Additionally, the study looks at the importance of the cultural dimension of an emerging leader, as it relates to the development of resilience. If hardships represent a significant role in leadership formation, then understanding this step is vital for the development of future leaders and leadership training in diverse cultural contexts. Everyone experiences some sort of hardship in life; however, effective leaders may intentionally use these obstacles as a training ground by overcoming them.
